For this, the user may need to cue a specific image in the video sequence by manually trying to find the image to be trimmed. This may further require that the user replays the entire video sequence again and again or to try and locate a point in the video sequence where the last video viewing session was aborted. This may be done for a pre-recorded video or a live video feed which is still being recorded. Such a process may be too time-consuming and prone to error due to dependency on manual speed of browsing through the video sequence.
